Hammerhead Karoo 2 bike computer
£323, hammerhead.io
Modestly described by Hammerhead as ‘the finest head unit ever built’, the Karoo 2 aims to bring bike computer technology a step closer to the smartphone. Hammerhead claims the Karoo 2 has twice the pixel density of its nearest competitor and the largest colour spectrum you’ll find. The glass touchscreen is designed to be functional whatever the weather, however the device can also be fully controlled using the four buttons – a handy inclusion for glove wearers.
Inside it has a quad-core processor, a monstrous 32GB of storage and is compatible with just about anything: Bluetooth, ANT+, Wi-fi, 3G and 4G, as well as GPS and other navigation systems.
Its versatile display has six different map options that offer route editing and have functions to get you home or to the local cafe. Meanwhile the 23 data page layouts can show everything from power and elevation to your electronic shifter battery levels.
The unit is 40% smaller than its predecessor, with its surface measuring 60.8x100.6mm. And you know what they say about small packages.
